Background. Diffuse pulmonary ossification is a rare disease characterized by diffuse microlithiasis-like nodular shadows in the lung. Although it is most common in elderly men, younger cases without underlying diseases have been reported. Case presentation. A 20-year-old man was evaluated in our hospital because of abnormal findings on chest imaging. A bronchoscopic examination was performed and a transbronchial lung biopsy showed bone tissue with fatty bone marrow. The patient was diagnosed with idiopathic diffuse pulmonary ossification. Conclusion. There are few cases of diffuse pulmonary ossification diagnosed by bronchoscopy. Bronchoscopy is a less-invasive procedure than thoracoscopic surgery and may allow for an early diagnosis of diffuse pulmonary ossification in clinical practice.
